Concern for impacts to groundwater resources due to coal seam gas operations has led to heated debate in the community. This project will assess the risk to groundwater contamination from fracking in coal seam gas operations. It is critical that naturally occurring compounds in the coal seam and injected compounds are not mobilised to aquifers topped by water bores. This project will build accurate, site-specific, dynamic numerical models of the hydraulic-fracturing process in coal seam gas operations. This will enable prediction of the maximum vertical extent of stimulated fractures in specific coal seams and will help establish criteria for when and where fracking in coal seam gas wells is safe in relation to groundwater contamination.

由于煤层气作业对地下水资源的影响引起了社会的激烈争论。该项目将评估煤层气开采中水力压裂对地下水污染的风险。关键是煤层中天然存在的化合物和注入的化合物不被调动到水钻孔顶部的含水层中。该项目将建立准确的，特定于现场的，动态的煤层气作业水力压裂过程的数值模型。这将能够预测特定煤层中受激裂缝的最大垂直范围，并将有助于建立关于煤层气威尔斯井中的压裂何时何地相对于地下水污染是安全的标准。
